Wzmacniacz pomiarowy kanały: 2 +125°C 3 → 5,5 V Różnicowe Skyworks Solutions Inc 8 -pinowy

Izolowany wzmacniacz do pomiaru prądu bocznikowego SI8920. The Si8920 is a galvanically isolated analogue amplifier. Their low voltage and differential input is ideal for measuring voltage across a current shunt resistor or for any place where a sensor must be isolated from the control system. Output is a differential analogue signal amplified by either 8.1x or 16.2x. The very low signal delay allows control systems to respond quickly to fault conditions or changes in load. Low offset and gain drift ensure that accuracy is maintained over the entire operating temperature range. High common mode transient immunity means that the Si8920 will deliver accurate measurements even in the presence of high power switching like would be found in a motor drive system or inverter. To help evaluate the Si8920 there is a dedicated development kit available - SI8920ISO-KIT (RS 9026806). It is populated with the Si8920BC-IP and enables quick connection to a shunt resistor. Model Si8920 jest dostępny w 4 wariantach: SI8920AC-IP (RS ; 901-3967 901-3967 ) z zakresem wejściowym ±100 mV w pakiecie Gull-Wing DIP-8 SI8920BC-IP (RS ; 901-3976 901-3976 ) z zakresem wejściowym ±200 mV w pakiecie Gull-Wing DIP-8 SI8920AD-IS (RS ; 901-3979 901-3979 ) z zakresem wejściowym ±100 mV w pakiecie SOIC-16 SI8920BD-IS (RS ; 901-3973 901-3973 ) z zakresem wejściowym ±200 mV w pakiecie SOIC-16
